PRINTING-PRESS DELIVERY-BOARD.

To all whom it may concern:

Be it linown that I, MICHAEL A. Dnorrconn, a citizen of the UnitedStates, residing in Chicago, in the county of Cook and State ofIllinois, have invented a new and useful Improvement in Printing-PressDelivery- Boards, of which the following is a specification.

This invention relates to the construction of high speed printingpresses and its object is to avoid the stoppage or slowing down of thepress while changing or emptying the delivery tables.

The nature of the invention is fully disclosed below and is alsoillustrated in the accompanying drawing in whicli- Figure 1 is atransverse vertical section of the delivery end of the press; Fig. 2 isa section on the line 2 2 of Fig. 1 and F ig. 3 is a side elevation ofone of the members of the screw frame by which the tables are lowered.

In said drawing 4L represents the tape roller carrying' the tapes 5 bywhich the sheets are brought to and dropped upon the delivery tables. Ishow a plurality of these tables, 6 being the main or lower one whichrests upon the L-shaped supports 7 which are united to the nuts 8mounted upon the adjusting screws 9 at the corners of the table, thescrews being geared to the hand operated shaft 10 having operating wheel11 adapted to give motion to the screws at both ends of the table andalso to the shafts 12 at the sides of the table, by which the screws atthe back are made to move in unison with those at the front. Thesupports 7, it will be noticed, are adapted to .permit the table to betaken out edgewise with the accumulated sheets thereon and the table isalso provided with guards 14 to prevent the sheets of paper from slidinglaterally while being delivered.

When the desired number of sheets have accumulated upon the table (i, Iinsert in the channel iron supports 15 which are stationarily secured atthe upper ends of the side members 16 of the screw frame, a very lighttable which may be desirably made of a surrounding frame 17 with a wovenwire center 1S. This table which I call the temporary table is so lightthat it can be inserted in place over the table G without stoppage ofthe press or slowii'ig down, and it Specification of Letters Patent.

is intended to remain in acting position only long enough to permit theremoval of the table (3 and its accumulated sheets, or the placing inposition of a second table (5 over table (3 as shown in Fig. l. Thistable is also preferably provided with guards Il; at each end. As soonas the changes have been made in the main table or the supplementarytable Ga, the table 17, 1S is removed with the few sheets which willhave been deposited upon it.

`\Vhen desired the main table is lowered on to the truck 19 and removed,the light table 17 being in position while this is done.

By this invention I entirely do away with thenecessity for stopping thepress and l am enabled to take care of the sheets without slowing downand no damage is done to the delivered sheets.

The side members 1G are preferably bracketed to t-he frame 20 of thepress by brackets 2l.

Operation: The sheet receiving devices are located at the delivery endof the press as usual and the sheets are fed by the delivery mechanismonto the receiving table (3 when it is in'uppermost position; and when asuitable number of sheets have accumulated thereon a supplemental tableGa is slipped on table (3 over the accumulated pile of sheets, asindicated in Fig. 1, and the table G is then lowered an extent equal tothe height of the guards 1l; when the supplemental table Ga is filledanother one is placed on top of the same to be filled with sheets,- thetable G being lowered as the supplemental tables are placed thereon, themain table G being ultimately lowered upon the truck 19. Then the loadedtruck is removed. The truck and the receiving and supplemental tablesare old per se, and heretofore it has been necessary to stop the presseach time a supplemental table had to be inserted or removed-and alsowhen the truck had to be removed. By aid of my invention thesupplemental tables can be inserted whenever desired and the loadedtruck can be removed and replaced when desired without stopping theoperation of the press or the delivery of the sheets. I am enabled to dothis by use of the light removable table or sheet catcher 17 which, asabove explained, can be easily and quickly inserted in, or removed from,the guides 15 between the de- Cri livery and receiving tables in theshort interval of time between the delivery of two successive sheets.IVith my invention when the operator desires to insert anothersupplementary table Ga or to remove the truck, he takes the removabletable or sheet catcher which is normally out of the 1nacl1ine,-in sertsits edge in the guides l5 and then, as soon as one sheet drops, quicklythrusts the sheet catcher into place so as to catch the following sheet;and the succeeding sheets will be also caught thereby, giving theoperator time to lower the main table and insert another supplementaltable or change the trucks. Then the operator has the parts again inposition desired for receiving the sheets on the main or supplementaltable, he simply quickly withdraws the removable sheet catcher andsheets accunmlated thereon, without. stopping the delivery of thesheets, the latter simply dropping onto the supplemental or main tableas bei'ore. By this arrangement I do not require any automatic loweringof the main table as this can be done by hand.

I claim l. In combination with the sheet delivery mechanism of aprinting machine and a receiving table upon which the sheets aredelivered, of supports above the table and below the delivery and alight removable sheet catcher adapted to be placed on or removed fromsaid supports in the intervals between the delivery oit' successivesheets, and when Uuayxao inserted to receive the sheets delivered fromthe press while the tables are being adjusted, inserted, or removed.

2. In combination with the` delivery mechanism oit a printing press, avertically adjustable sheet receiving table, and supplemental sheetreceiving tables adapted to be placed on the receiving table, ot'supports for a sheet catcher located intermediate the delivery mechanismand the receiving table, and a light removable sheet catcher adapted tobe placed by hand on the said supports, or removed therefrom, in theintervals of time between the delivery of successive sheets, saidcatcher when inserted holding the delivered sheets while the operator ischanging the tables.

In combination with the delivery mechanism of a printing press, andremovable sheet receiving tables on which the sheets are delivered, of alight removable sheet catching table or sheet catcher adapted to beinserted by hand in position between the delivery and the tables, orremoved from such position in the intervals of time between the deliveryof successive sheets and without stopping the press, said catcher wheninserted receiving and holding the sheets delivered while the operatoris changing or adjusting the tables.
